My incisors have ongoing resorption even though no force is being applied to them. Could calcium hydroxide treatment stop it? Resorption has continued despite completely removing the anterior force after the radiograph three months ago.

External resorption caused by orthodontics cannot be stopped by endodontic treatment. Endodontic treatment can stop resorption only in internal resorption cases. If resorption still appears to progress after the force has been removed, this may be due to the angle of the radiograph. If the tooth is vital, root canal treatment is unnecessary; if orthodontic forces have caused it to become non-vital, root canal treatment can be performed.
